I am getting very close on making a GNU compiled C extension for PHP4 using ext_skel. Where does one look to understand what is going on inside the config.m4 file (m4 files in general) It is a mystery on how to make a shared library .so file available to PHP4. That is the problem. How to go from a --enable-modname format where the extension in compiled into libphp4.so to a shared library .so file where PHP4 can use the dl("TEST.SO) call to make those functions available. Any help and tips would be appreciated.
